Sauté the Aromatics – Heat olive oil in a large pot over medium heat. Add onion, garlic, carrot, and celery. Cook until softened, about 5 minutes.
Build the Base – Stir in Italian seasoning and red pepper flakes. Add crushed tomatoes and chicken broth. Bring to a simmer.
Add the Chicken – Stir in shredded chicken and let the soup simmer for 10–12 minutes.
Cook the Pasta – In a separate pot, cook pasta until al dente. Drain and add to the soup (this prevents overcooking).
Season & Finish – Taste and adjust with salt and pepper. Ladle into bowls.
Make it Parmesan-Style – Top each serving with mozzarella and Parmesan cheese. Let the cheese melt over the hot soup. Garnish with basil or parsley.
